ISO speed brake switch/button under King autopilot/trim yoke switch

Recommended Posts

In the process of upgrading my panel and interior, I would like to move my speed brake actuator button from the panel to my yoke. I have seen several setups where the button is mounted on the pilot's left yoke horn under the autopilot/trim switch of the King A/P. I contacted Precise Flight to find out how to get the switch and was told they do not have it and have no record of having it. So I am reaching out to the collective memory of MS to see if anyone knows how I can obtain one of them. I have seen them mostly on the K models, but do not think it is model specific. Anybody have any suggestions? TIA

Edited to add picture.

What I am looking for is the piece approximately 1/2" thick under the trim switch. The one in this picture has lost most of its color, but shows location and size. Red actuator button is on the left side.

I have a K model, 25-2026, with electric speed brakes.  My push-button switch is mounted on the left side of the pilots yoke, horizontally.  I can get you a picture, but I don't thing the switch is any special BK part.  It appears to be just a standard spring loaded switch.

Thanks, Bryan. That would be great.

That switch is Mooney Part# 01265.  I'd have to check with them on Monday for pricing.  Agree there's probably one or more equivalent push-button "click-on, click-off" type switches at places like Mouser or Greybar.  Unless anyone else has this covered, happy to dig and see what I can find out.

He's talking about the black button mounted horizontally on the far left side of the yoke (the top photo in Brian's post), not the red A/P Disconnect button on top.

Specifically, I am looking for the piece the black button (p/n 01265) is mounted on. I would agree it almost looks like a BK part as it has the same footprint as the autopilot/trim switch. Right now, mine is mounted on my panel, and switching it on and off takes eye movement to see where I need to push. Not a critical issue, but anytime I can limit my eye movement during approach or departure, I am all for it.

Thanks.

I’m talking about the extension piece that the switches are mounted on, not the switches themselves.

Thanks TJ...yeah, you're right - I didn't read carefully enough.

John, did some more looking.  You need PreciseFlight Part# M21-F12, or Mooney Parts# 950207-001 (spacer) and PB-12331ZQ (switch), or possibly MPA106D with 1825068-1 button.

Let me know if this helps.  Sorry for any misdirection (edit).

Steve, perfect hit on the Mooney p/n. LASAR lists the part but is sold out. Now that I have the id of what I need, I can extend the search. Thanks again.

You're welcome...thanks to TJ's correction.  :-)

Lance beat me to it...DigiKey has always been good.  Not necessarily the cheapest, but they've had things others haven't.

Let us know how you make out?

This is the part I am searching for. It is the 950207-001 part number. I have everything else and just need this one final piece. I would even be willing to make it as an "owner created" part if I could get all of the specs.

Thanks for all of the info guys.

Off topic, but I noticed what appears to be a rounded plastic button on the CWS switch. All mine has is a little protuberance which is a bit on the sharp side, making for painful use. Is that plastic piece factory or did you fashion it yourself?

You may have to do a little research by Googling pushbutton switch caps or something like that.

This is what I found after about 3 minutes of looking:

Most of the push-buttons have a "cap" atop the shaft to spread out the load when pushing the button.  This CWS button came from the factory this way.  My guess, you lost your "cap" for the push-button.  You have to remove them when replacing the switches to get them to go back down into the hole to be removed.  You might be able to find a replacement cap/button at a RadioShack or the internet.  The cap just pulls off and pushes on.

Finding the correct size could be a problem.

You refer to Radio Shack. What's that?
